physiofit's Issues

crossprod error

Hello @pierremillard,

I've been trying to play with PhysioFit and I got an unexpected traceback with the following code:

source("./PhysioFit-master/physio_fit.R", chdir=TRUE)

res = physio_fit(datfile="example.txt")

(I use a copy of PhysioFit extracted from the archive on the master branch. The example file is a copy of the file shipped in the example folder.)

console + traceback:

Initialize the system...

Dear all, after installing PhysioFit I get the following error when trying to launch the PhysioFit GUI. I am on Windows using Anaconda Navigator 2.3.2
Any help would be appreciated.
